滚子轴承中的弹性接触问题是摩擦学领域重要课题。作为对接触问题的实验研究,本文对古德尔发表的测量接触区形状“Footprint”法进行了改进。采用新的实验措施后,不用准备大量的修正数据及曲线,就可得到更精确的实验结果,因此,改进后的实验方法具有操作简单,费用低廉的特点,还可推广应用于各种接触问题的实验研究。附图8幅,表3个,参考文献4篇。 The problem of elastic contact in roller bearings is an important issue in the field of tribology. As an experimental study of the contact problem, this article improves on the Footprint method of measuring the shape of the contact patch published by Goodall. After adopting the new experimental measures, more accurate experimental results can be obtained without preparing a large amount of correction data and curves. Therefore, the improved experimental method has the advantages of simple operation and low cost, and can also be widely applied to various contact problems Experimental study.
